withTStringBuffer :: Int -> (LPTSTR -> IO a) -> IO a

Marshal a dummy Haskell string into a NUL terminated C wide string using temporary storage.

• the Haskell string is created by length parameter. And the Haskell string contains only NUL characters.
• the memory is freed when the subcomputation terminates (either normally or via an exception), so the pointer to the temporary storage must not be used after this.

withTStringBufferLen :: Int -> ((LPTSTR, Int) -> IO a) -> IO a

Marshal a dummy Haskell string into a C wide string (i.e. wide character array) in temporary storage, with explicit length information.

• the Haskell string is created by length parameter. And the Haskell string contains only NUL characters.
• the memory is freed when the subcomputation terminates (either normally or via an exception), so the pointer to the temporary storage must not be used after this.
